Local matting process adopting sequence of earlier hot stamping and later printing

Abstract

The invention discloses a local matting process adopting a sequence of earlier hot stamping and later printing. The local matting process comprises the following steps of adopting a deckle edge hot stamping and printing draw gauge positioning technology and using a corresponding hot stamping and printing forme and an alignment film, and overprinting cross lines the hot stamping and printing forme to ensure the accurate sleeved position and smooth and firm hot stamping and printing surface, wherein a hot stamping and printing material is UP100, and a flat hot stamping mode is adopted during hot stamping; adopting an aluminum laminated film coating as a water carrying prime coat, using a varnishing machine to achieve varnishing, controlling the speed of the varnishing machine and ensuring smooth, even and proper-thickness varnishing, wherein no abrasion mark is produced on the surface of the hot stamping and printing position; firstly using specific-color ink and wired UV gloss oil to perform printing, then performing pressing-printing ink fountain matte varnishing printing, wherein attention is paid on the pressing-printing ink fountain matte varnishing fastness in the step, an error at the position of the overprinted hot stamping and printing material is smaller than or equal to 0.2mm, and an varnishing overprinting error is smaller than or equal to 0.1mm. In the local matting process, a digital image and video positioning technology and the deckle edge hot stamping and printing draw gauge positioning technology are adopted to ensure accurate positioning of local hot stamping and printing positions and deinking-free matte varnishing printing.

Description

[0001] technical field [0002] The invention relates to a partial matte printing process after hot stamping, which belongs to the technical field of packaging and printing. Background technique [0003] With the improvement of people's consumption level, my country's cosmetics market is growing rapidly at an average annual rate of 20%, and the cosmetics packaging industry has also developed rapidly. In order to improve the attractiveness of cosmetics to consumers and enhance their own brand value, cosmetic packaging technology is also paying more and more attention to the printing process of packaging. [0004] Because it can highlight the design theme and have a unique three-dimensional visual effect, the hot stamping and printing process has gradually been promoted and applied in the field of packaging printing, and has been favored by many enterprises and consumers. Hot stamping first, refers to a process of hot stamping first, and then printing on the surface of the ho...

Problems solved by technology

[0006] At present, there are the following problems in the packaging products processed by the commonly used process of hot stamping first and then printing: 1) The positioning of the hot stamping on the paper pattern is not accurate, and misalignment leads to bad printing, so the hot stamping accuracy is low

2) The ink adhesion of the hot stamping part is not high, the ink on the packaging surface is not firm, the surface is easy to scratch during packaging, transportation or use, and the phenomenon of ink loss is serious
